Passivhaus, Dulwich Estate
Herne Hill, South East London
A whole house refurbishment and extension of a 1930’s property in Herne Hill located within the Dulwich Estate. The project includes a contemporary single storey rear extension to create a large open plan kitchen, dining and living space. Space has also been found in the existing house to locate a new shower and utility room at ground floor. Large, glazed ,sliding doors on the rear facade, together with the continuous polished concrete floor provide a direct connection between the spacious open plan living area and garden.
The house has been retrofitted to drastically reduce energy use, household bills and carbon dioxide emissions. Using Passivhaus principles, the measures include; under floor insulation, upgraded roof insulation, double glazing, airtightness measures and the installation of a whole house ventilation system with heat recovery, photovoltaic panels, high efficiency boiler with large thermal store and solar thermal panels. The works also include bespoke built in furniture design and landscaping to the rear garden.
A temporary kitchen was setup up for the residents during construction work, which along with careful planning and some flexibility on all sides allowed the work to be undertaken without the residents moving out.
